> Existing udf get_json_object supports limited JsonPath syntax.
> It would be nice if we have full JsonPath syntax support.
> We can use Jayway JsonPath 2.0.0 to query json (Apache License, Version 2.0)
> Reasons:
> 1. existing get_json_object syntax is limited in comparison to Jayway JsonPath
> 2. get_json_object uses lots of custom java code which can be replaced with 
> simple JsonPath API calls, e.g.
> {code}
> Object result = JsonPath.parse(json).read(path)
> {code}
> I think we should not change existing get_json_object udf and better to 
> create new one because Jayway JsonPath works slightly different in some 
> situations.
